If you list a band as a feature or main artist, you can't also list the members of the same band individually as main artists or features. An entry such as "The Beatles feat. Paul McCartney" is not permitted. In this case, you would have to delete the band members from the metadata (basic information / track list) and only list the band as main artist.

1.9. Artists and Artist Names

Multiple artist names must not be used solely to increase the visibility of products on Spotify. Any products found doing so will be removed from Spotify. Violation of this rule could result in a strike or block in accordance to the Spotify Content and Infringement Guidelines.
